Tree Height Growth

Plants were grown in a 2 × 2 factorial combination of planting depth in nursery containers and at a landscape installation to study effects on root architecture, growth, and mechanical stability of Magnolia grandiflora L. Planting depth into containers or landscape soil had no impact on bending stress to tilt trunks 40 months after landscape planting, and impacted neither trunk diameter nor tree height growth 68 months later. Trees planted 128 mm deep into 170 L containers had more circling roots at landscape planting and 68 months later than trees planted shallow in containers. Root pruning at landscape planting reduced the container imprint rating on the root system to one-third of that absent root pruning with only a 4 mm reduction in trunk diameter growth over 68 months. Improvement in root architecture from root pruning likely outweighs the rarely encountered downside of slightly less anchorage in an extreme weather event simulated by winching trunks. Trees planted 5 cm above grade were slightly—but significantly—less stable in landscape than trees planted deeper (10 cm below grade). Root pruning at planting to remove roots on root ball periphery appeared to improve root architecture while only slightly impacting growth and anchorage.

Abstract A wild-type selection of heavenly bamboo (Nandina domestica) and ten cultivars were evaluated for plant performance, growth, flowering, and fruiting in north and south Florida. Onset of flowering generally began by March and April in south Florida and 4 to 8 weeks later in north Florida. Fruit was first noted 8 to 16 weeks after most selections began flowering. Landscape performance and fruit production varied widely among taxa and locations. The dwarf selections ‘Filamentosa’ and ‘Firepower’ failed to flower or fruit in either location; while the medium-sized selection, ‘Moon Bay’, did not flower or fruit in south Florida, and the medium-sized selection, ‘Gulf Stream’, flowered but did not fruit in south Florida. Large-sized selections produced more fruit than did dwarf and medium-sized cultivars. Greater plant survival with generally heavier fruiting was observed in north Florida than in south Florida. In north and south Florida, ‘Monum’ and ‘Compacta’ produced more fruit than did the wild-type selection. Seed viability was fairly consistent among cultivars, ranging from 73 to 86%.

Abstract Seven groups of seedlings from each of seven single parent (half-sib) families of sycamore, Platanus occidentalis L., were grown to a marketable size in 9.1 liter (#3) containers to test responses to container nursery production in south Texas. Seedlings were then transplanted to a field site (Brazos County, TX) in the fall, spring, and summer to assess seasonal effects on landscape establishment. Regional selections grew larger, both during container production and following subsequent transplant to the field. Growth of nonimproved local half-sib families equaled or exceeded that of genetically improved families from a distant region. Differential responses among genetically improved and non-improved sources were less pronounced when genotypes were grown in a region from which they did not originate. Fall and spring transplanted seedlings had substantially greater growth and survival than did summer transplants regardless of genotype. This study demonstrates a potential for regional market segregation of seed-propagated landscape trees.

The Impact

Landscaping today involves the struggle to balance aesthetically pleasing plants while minimizing the impact on the environment, reducing water usage, decreasing fertilizer use, and eliminating or significantly reducing pesticide usage. Roses (Rosa sp.), although seen as challenging plants, remain the most popular flowering shrub in the United States. The identification of new cultivars that combine beauty, pest and disease resistance, and drought tolerance are important to Texas landscapes. Sixty roses were assessed over a 3-year period to determine flowering, drought tolerance, disease resistance, and overall landscape performance in minimal-input gardens in north central Texas. Atypical weather during the study had a significant impact on performance. A 2-year drought (2010–11) was accompanied by the hottest summer on record (2011), which included a record number of days of at least 100 °F or higher. As a result, supplemental irrigation was provided three times both summers. Roses generally fared well under these conditions and survived the drought. Flowering was most abundant during the spring and fall, and it was least abundant in the summer. Powdery mildew [PM (Sphaerotheca pannosa var. rosae)] was a minor problem. Nine of 60 cultivars developed no visible symptoms of PM during the study. Most PM occurred in Spring 2010, with very little found after June; none was found in 2011. Black spot [BS (Diplocarpon rosae)] was serious for some cultivars, but most were BS-free; RADrazz (Knock Out®) and Lady Banks White had no observed BS during the study. BS occurred mostly in May, June, and November. Overall landscape performance ratings were high, with 23 cultivars having a mean landscape performance rating equal to or better than the Belinda’s Dream standard. The best-performing cultivars were RADrazz (Knock Out), RADcon (Pink Knock Out®), RADyod (Blushing Knock Out®), WEKcisbaco (Home Run®), and Alister Stella Gray. This study was able to identify many other highly performing roses in north central Texas.
